To r/.ZZ whom it may concern.'

Be it known that IVILLIAM l). Jonson and HARVEY S.k Somma, citizens ofthe United States, residing at Philadelphia and Scuderton, in thecounties of Philadelphia and Montgomery and State of Pennsylvzmia,

tion is to provide `an improved form of continuously operatingcentrifugal amalgamator.` y

A third important object of the invention is to provide, in a device ofthis class, an improved arrangement of amalgamating chamber. l

A fourth important object of the invention is to provide an improvedarrangement and combination of inlet and outlet pipes in such anamalgamator.

With the above and other objects in view, the invention consists ingeneral of certain novel details of construction and combinations ofparts hereinafter fully described, illustrated in the accompanyingdrawings, and specifically claimed.

The drawing shows a. vertical median section through an amalgamatorconstructed in accordance with this invention. n

In carrying out the invention there is provided a lower frame member 10and an upper frame member 11. These members are connected by spacingbolts 12 andbetween the two frame members is an interme diate framemember 13 also supported on these bolts. Mounted in the lower framemember 1() is a foot-step bearing 14C and in the member 13 is a. bar 15.Extending through these bearings is a drawoii' or eX- haust pipe 16having a collar 17 resting on the bearing 14 and a second collar 18resting on the bearing 15. Between the frame members 10 and 13 is aframe member 19 carrying a bearing 20 wherethrough extends a'shaft 21driven by some suitable means, as for instance a belt surrounding apulley 22.

Onthe shaft 21is a `bevel gear 23 which meshes with asimilar .gearl 24fixed to. the

exhaust pipe 16. Screwed on to the upper end of the exhaust is an outeranlalgamator bowl 25 and inner amalgamator bowl 26 is likewise screwedon tosaid pipe above the connection with the bowl 25 so that the innerbowl is held in spaced relation to the outer bowl. The exhaust pipe 16thereinis well uptoward the top of the bowl 26 as shown in the drawing,

Carried by theupper framemember 11 is a bearing 27 through which extendsa supply pipe 28 fixed to the bowl 25 and communicatingwith the clearopening 29 of said bowl. In the upper end ofthe pipe 28 is a connection30 by` means of which this pipe maybe connected to a. supply pipe. Thepipe 30 entendsdowny in a rabbit 31 formed in the pipe28 and the bearing2i' is arranged to act as a. packing gland to hold suitable packing 32around said pipe 28. By this means the slimes can befed down.-

` ward through they pipe 28 intothe outer bowl 25.

In the lower part off the bowl 26 there is provided a plurality of ports33 and similarly ports 34 provided with stop plugs 35 o-pen from thebowl 25 outwardly. The

port 33 afford communication from the space between the inner and outerbolts-to the space within the inner bowl. It will be noted that betweenthe openings 33 the inner bowl ispprovided with an upwardly extendingboss 36 having a bevelled upper surface 37 which forms a run-off surfaceand prevents accumulationI in the inner bowl with the consequent gradualhardening and the collect-ion of a mass of amalgam around the draw-offpipe. K.

In operation they bowls are set inrapid rotation by means of the beltpulley 22. The slimes are then fed downward through the pipe 28 andpassed into the space between the inner and outer bowls. A quantity ofmercury M is placed in the outer bowl and due to the centrifugal actionof the rotating bowls the mercury rises between the bowls. The slimesare forced down through past mercury and, on reaching the ports 33 passthrough these ports and rise up within the inner bowl, the drossbeing'lighter than the mercury. As the slimes pass the merY cury thegoldcontained therein amalgamates' dross passes upward and overflows thetop of the exhaust pipe 16 down which it passes fromthe'ai'nalgaifnatoix From time to time the plugs 35 are removed and theamalgam drawn oft, fresh inercuiy being supplied at such'jt-iniesthroughthe pipe 28.

ff There has thus beenfprovided a simple and efficient device of thekind described and for the purposes specified.

It is 'obvious that minor changes may be made in the form andconstruction of the invention without departing"from the niaterialprinciples thereof. i It isinot therefore desired "toconne the invention.to the exact forni' herein shown and described, but it is lwished'toinclude all such as properly come within the scope claimed.

Having thus 'described the invention, what is i claimed new, 'is

l. na'n ainalgainator, a frame, an eX- haust pipe journalled verticallyin said fra-ine, an l.outer bowl screwed on' ,the upper end "ofsaid'pipe, an' inner bowlA screwed on the upper end of said pipe abovethe connection oi the outer bowl thereto, said` bowls being arrangedwiththeir sides and tops in spaced relation, said pipe terminating. near thetop ofi-*the inner bowl, said inner `bowl 'having ports opening into thespace between the bowl and the outer bowl having norinallyclosed" drawoil1 ports, said inner bowl having an upwardly extending boss sur#"rounding said" pipe'and projecting above the openings, vthe boss beingprovided with a IfriistoE-conical upper end., anv inlet pipe' ]our-'nalled veiticallyrin thefiame and communicating 'Withthe y'top oftheouterbowl ,and

'having' a'fcounter sunk portion in itsiipper end, apipe connectionhaving the same internal diameter as the inlet pipe and fitted. withinthe :counter sink of said inletpipe to swivel in relation thereto andmeans to rotate said bowls.

2.111 an"""amalgamator, a traine, an exhaust pipe journalled verticallyin said openings, ythe boss being provided with a frusto-conical upperend, an inlet pipe journalled vertically 11i the-'frame andcjommuni-'eating with the top ofthe outer bowl and having a counter sunk` portionin its upper end, a pipe connection having the same internal diameter asthe inlet pipe and fitted within the counter Ysink 'of said inlet pipe'to swivel in relation thereto, and' means to rot-ate said bowlscomprising a bevel gear iiXed to the exhaust pipe'. a second'bevel gearmeshing with the iirst gear, and adifive shaft journalled in the vtraineand carrying p the secondbevel gear. v
